the car pulling to either sides is more than just "toe"
Like you have mentioned it can be a tire pull,but does your truck have caster adjustment?Cause some bad caster will make the car pull bad,no matter how centered the wheels are..

Also when you changed the tie rod ends,did youjamaican
ut the new ones on about the same estimated turns?

EX) like if you took the left tie rod off and it was 20 turns,put the new one on @ 20 turns..

Maybe the frame has damage?Theres alot of things to look at than just my steering wheel is not straight.did you get a computer read out? if so I want to see a copyt..
